Because c the speed of electromagnetic radiation is a constant the wavelength of the radiation is....?
PrinceErick
The wavelength is inversely proportional to its frequency. That is, as the frequency increases, the wavelength decreases and vice versa.

The best flame for heating thing is?
The best flame for heating thing is blue. Complete combustion usually has a dim or light blue color because of single wavelength radiation.
Does light have substance?
Not exactly. Light from the sun consists of electromagnetic radiation. We can tell this is so because sunlight has a range of colours emitted, which has wavelengths that are within EM spectrum.
Why a metal bar expands when it is heated?
Because the electrons in the atoms of the metal are being excited to a higher energy level they must "de-excite" and go back down to a lower level. When this occurs EM radiation is given off. If this radiation is in the visible light domain it will have an associated wavelength. This wavelength happens to be in the visible spectrum of red/orange/yellow light when metal is heated. Also, there are other types of non-visible radiation when heated, i.e. IR radiation.
Can A photon of low frequency light has more energy than a photon of high frequency light?
Yes. The energy is given by plank's constant times the frequencie of the photon (remember that light is both particle and wave). So since blue light has higher frequency than green light, it is more energetic.
What are two examples of radiation?
A simple example of radiation is to turn on a light-bulb, and bring your hand close to it. The closer your hand gets, you begin to feel the heat from the light bulb. This is radiated heat energy. As soon as you turn on the light-bulb, even before you bring your hand close to it, you SEE it, because of the electromagnetic radiation in the VISIBLE range that leaves it. Another example of radiation can be a lava lamp. Radiation is the whole reason how a lava lamp works. Also there is ultraviolet, visible, infrared, gamma, microwave, X, alpha, beta, etc.
If you know the vacuum wavelength of any form of electromagnetic radiation you can determine its frequency because?
You know its speed in vacuum, and frequency = (speed) / (wavelength) .
What is the x in X-ray?
X Radiation is a form of Electromagnetic Radiation with a wavelength 0.01 to 10 nanometers. The letter X was selected because it signifies an unknown type of radiation
If the frequency of an electromagnetic wave increases the speed of the wave does what?
If the frequency increases, the wavelength decreases. Wavelength lambda and frequency f are connected by the speed cof the medium. c can be air = 343 m/s at 20 degrees celsius or water at 0 dgrees = 1450 m/s. c can be light waves or electromagnetic waves = 299 792 458 m/s. The formulas are: c = lambda x f f = c / lambda lambda = c / f
Which of the alpha beta and gamma radiation is formed of electromagnetic radiation?
We know that gamma rays are electromagnetic energy, and they'll occupy a place on the electromagnetic (EM) spectrum. You can locate gamma rays right at the top end of the EM spectrum because their frequencies are so high (or their wavelengths are so short, if you prefer).
Why is solar energy transfered to earth by radiation?
That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.
As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum what happens to the frequency of the light?
colour blue ------> red frequency drops, wavelength increases, because speed remains constant and speed=frequency*wavelength
Why fire is blue in colour?
Fire is blue in colour because of its radiation, when it is red hot its electromagnetic wavelength expands towards the red end of the visible spectrum but is also gives off infra-red radiation (heat) when the fire gets even hotter however, the electromagnetic wavelength shortens and goes towards the blue end of the visible spectrum, hope this helps :)
Does Infrared radiation has a longer wavelength than visible light?
Because that's the name we have given to the electromagnetic radiation at the end of the spectrum with the longest waves.
What is a visible ray?
"Visible" electromagnetic radiation is radiation with wavelengths between roughly 390 to 750 nanometers. (0.000350 to 0.000750 millimeters) -- If electromagnetic radiation with a wavelength in this range enters your eye, you know it, because the retina of your eye responds to these wavelengths. -- If radiation enters your eye but its wavelength is not in this range, you don't notice it. -- If there is radiation in the neighborhood with wavelength in this range but it doesn't enter your eye, then you don't notice it. (If a flashlight shines a spot on the wall across the room, you don't see the shaft of light on its way across the room. You see it only after the light hits the wall and some of it bounces off the wall and into your eyes. )
Why is the wavelength of a moving soccer ball not detectable to the naked eye?
Firstly, the "naked eye" can't detect the wavelength of any kind of electromagnetic radiation outside a very small window of frequencies that correspond to visible light. And secondly, Planck's constant is so small that the de Broglie wavelength of any macroscopic particle is infinitesimal.
What are the advantages of using telescopes to detect electromagnetic wavelengths other than light?
the advantage of this is by using the telkescope you can collect and focus radiation and it do not suffer from chromatic aberation because all the wavelength will redlect off the mirror the advantage of this is by using the telkescope you can collect and focus radiation and it do not suffer from chromatic aberation because all the wavelength will redlect off the mirror the advantage of this is by using the telkescope you can collect and focus radiation and it do not suffer from chromatic aberation because all the wavelength will redlect off the mirror
As the speed of a particle increases does its associated wavelength increase or decrease?
The wavelength of waves travelling with the same speed would decrease if the frequency of the waves increases. This is because, speed of a wave is the product of the distance of the wavelength times the frequency of the wave. The velocity of a wave is usually constant in a given medium.
